T (5Z3 whom it may; concern Be it known that L SIDNEY Wnnooiq, citizen of the United States, and residentof Detroit, il -sync councy, State of ldichigun, invented certain new and useful proveinents in Hydrocarbon Motors of which die following is a specification.

This invention relates to h 'drocarbou motors and particularly so the oiling system of such incisors.

There are two well known oilingsystems for lubricating the crank shaft and other hearings of hydrocarbon motors; first, the splash system in which a queue-it of oil is placed in izhe inclosed crank case and the crank shaft and connecting rods-splash 5 is oil to the various bearings within the case;

and second, the force feed system in whichoil is fed under pressure obtained by gravity or by a force pump direcily bo each of the bearings.

The present invention is shown as embodying a system of the latter type in which the crank case is formed with a drain com- Y partmen't or sump and the oil which drains into this sump is constastly circu using by a pump through pipe leads to the various motor bearings. and after passing through the bearings is thrown by the rotating parts into the crank case and from there again drains to the sump. Thus a constant circulation of oil is kept up through "the motor hearings and since the sump has considerable capacity the sys'em will take care of itself for a reasonable time. In practice, however, it has been founr that in a system of this chargcter the oil becomes thin and loses some of, its lubricating qualities as it is used over and over again, and heretofore becn necessary to replenish the supply from time to" time in order to keep up the quality of the oil.

One of the objects of the present invention is to automatically keep up the ouelit-v of she oil in a circulating s v "sin of She above referred so, and broadly, the invention comprises :1 cons system combined wit: means for constantly su iplying 1' 2 she circu ity of oil that some o t io c? o the oil l burned r v used of;

passing around the pistons into the cylinder and by possible leakage. which drain on the system is also taken care of bv the fresh oil supply.

Other objects of the invention will appear from the following description and the claims.

lo the drawings, Figure 1 is a side elevation and part longitudinal section of a hydrocarbon motor embodying this invention; Fig. 2 is 21 transverse section through the crank case? of "she motor shownin Fig. 1; and Fig. is a plan view of the crank case ich the motor cylinders removed.

The motor crank case 10 forms the base and support for the motor cylinders 11, shown as cost in pairs and mounted on the crank case in the usual way. The lower half 12 of qhe crank case is suitably secured to the upper half and it is formed with a sump 13 into which the oil drains through openings 1% after being thrown oil from the crank shaft and cam shaft bearings. The crank shaft is shown at .15 and the two cam shafts at 16, these shafts being supported in the crenk case and suitably geared together. i

In the sump 13 is mounted a circulating pump 17, shown as a gear pump, and the golrbrce. Thus it will be seen that there is a constant circulation of lubricating oil from the sump 13, through the pump 17 pipes 18 and 19 and the bearings 20 and then back into the sump through the openings 14.

For supplying fresh oil to the circulating system a tank 21 is mounted on the crank case and :1 pump 22 draws oil in measured fillllltllllfis from the tank and forces it through the sight feed 23 directlv into the crank case as by the pipe 24:. It will, of course. understood that from the crank the fresh oil mingles with the other oil herein and flows througlf'the openings 14 etc the sump. The tankis m'ovided with "so ile filler cap 33 and sight glass 34.

pump 17 and the pump 2:2 may be riveu o a single pump operating shaft 25 r to and through the oil tank 21, for the dual purpose of serving as a breathing pipe and of keeping the oil in thetank warm and in flowing condition. The upper end of the tube 29 is provided with the usual screen 30.

In order that the amount-of oil in the sump may be easily determined a float 31 is 'tached to the float and extends provided and an indicator stem 32 is atupwardly through the tube 29 and the screen 30 to a position where it may be observed by the operator. r

Having thus desc bed my invention, what I claim is:

1. In a hydrocarbon motor, the combination with the crank case adapted to contain a quantity of lubricating oil, and means for constantly circulating the crank case oil from and to the crank case, of independent means operated by the motor for supplying fresh oil to the circulating system.

2. In a hydrocarbon motor, the combination with the crank case adapted to contain a quantity of lubricating oil, and means for positively feeding the oil in the crank case to the crank shaft bearings from whichit may return to the crank case,.ofindependent 4 means operated by the motor for supplying supply tank, and means fresh oil to the crank case.

' 3. In a hydrocarbon motor, the combination with the crank case having a sump adapted to contain a quantity of lubricating oil, an oil circulating pump and leads therefrom to the crank shaft bearings for supplying oil to said bearings from the sump, means whereby the oil supplied to said bearings returns to the sump, an auxiliary oil operated by the tion with the crank case having a sump adapted to contain a quantity of lubricating oil, an oil circulating pump and leads therefrom to the crank shaft bearings for supplying oil to said bearings from the sump, means whereby the oil supplied to said. bearings returns to the sump, an auxiliary oil supply tank, and a pump for feeding the oil from said tank to the crank case in measured quantities.

5. In a hydrocarbon motor, the combination with the crank case and motor base, of an oil tank mounted on the motor base, a pump in the crank case for circulating the oil therein, a pump outside the crank case for feeding oil to the circulating system, a shaft for driving both said pumps and means for operating said shaft from the motor crank shaft.

6. -In a hydrocarbon motor, the combination with the crank case and motor base, of an oil tank mounted on the motor base, a pump in the crank case for circulating thg-v oil therein, a pump outside the crank case for feeding fresh oil from said tank to the circulating system, a shaft for driving both said pumps, a spiral gear on said shaft, and a spiral gear onthe motor cam shaft for driving said pump shaft. v

'4'. In a hydrocarbon motor, the combination with the crank case adapted to contain a quantity of lubricating oil, and an oil supply tank mounted on the crank case, of a breather tube for the crank case passing through said oil tank, a float in the crank case, and an indicating rod on said float passing through said breather tube to a point where it may be observed for indicating the oil level II). the crank case.

In testimony whereof I affix my signature in the presence of two witnesses.
